Definitely a fixer upper, like $25/foot for interior, exterior, landscaping, asphalt improvement.

I could also give you some standard per foot or piece count prices on some of the basic things like paint, carpet, or a new water heater. 

vlad, I would think you could dissect the comps more: square footage, locations, amenities and make some adjustments to get a ball park number .they may have been all over, but may help you make the "reasonable offer" if you can study them some and maybe get what  duplexes are going for on a sq foot basis in the vicinity, a factor which may still work in your favor as you will be newer and probably better conditon with a new/newer build...

I ended up having G-Mac Construction (great company)  dig the outside of the basement wall down to the footing, I pushed the wall back out as far as I could using the I-beams, I cleaned the wall, I had a rubber coating sprayed on the the wall (a company recommended by G-Mac), I put in drain tile and G-Mac back-filled with sand then dirt.

To build anything you build from the ground up, begin digging the footings in your education and knowledge, pay attention to the framework, surround yourself with those smarter than you in their fields of expertise.

Wait till the agent logs in while willy nilly is logged in under a different IP, bingo, you're caught!

Get a good 12-gauge, 100-foot cord to go with it. 

I don't know about connecticut, but here in tennessee I am averaging $2.5/square foot.

Essentially, you are paying for something you hope you never have to use....but if it does happen, you have multiple parties in your corner fighting off a claim, for many years if needs be, and even if the limits of one were exhausted, you have another...and the legal fees alone could be large, so nice to have the insurers footing that bill and having an interested in settling or disposing of the suit....great question, though, could you be overinsured?

I think its important to be precise in describing this because there is a big stigma to an actual eviction, and inaccurately labeling it as this could be getting off on the wrong foot with your tenants.
